splendid thread, and great pics - are these all your own work? there are some fine, fine pieces here.

i work with a lot of glass crafts folk, and stealing an idea on PP we will be collaborating "at some point" to make coloured/patterned glass blanks for knapping - it could take quite a while before this happens, but it would be by the summer i expect to co-incide with a glass exhibition we host where i work - more info when and if it happens

Opal's lovely to work with, managed to get hold of a load of yellow stuff, as in the first pic, but haven't seen any at a reasonable price since. Easiest stuff around to knap, probably less than a quarter as tough as glass.
